Purpose - This study aims to examine the relationship between Chinese employees' collectivism orientation and organizational commitment and interpersonal helping behavior and verify the differences of such relationships between new and the previous generation of employees. Design/methodology/approach - The 262 Chinese employees participated in self-reported survey through online platform. The confirmatory factor analysis and the hierarchical regression analysis were performed to test hypotheses. Findings - We found that Chinese employees' collectivism orientation positively influenced their organizational commitment and interpersonal helping behavior. Regarding the moderating role of generation, our result revealed that while the positive relationship between collectivism orientation and organizational commitment was significant for previous generation of employees, such relationship was not valid for new generation employees. However, there was no significant generational difference in the relationship between collectivism orientation and interpersonal helping behavior. Research implications or Originality - Considering that there have been relatively few empirical studies examining the interaction between employees' cultural characteristic and generations, this study contributes to demonstrate that the positive influence of Chinese employees' collectivism orientation on organizational commitment vary depending on Chinese generations. In addition, this study provides implications that organizational leaders in China should understand that the generational difference can influence how employees' collectivism orientation leads to their attitudes towards organizations and need to establish human resource management system by reflecting generational difference.

Today's customer service providers, who have the greatest impact on customer satisfaction, are experiencing severe stress and job burnout due to various causes. Unlike general companies, the corporation has a relatively high level of dissatisfaction with customer service since there is a large conflict between the provision of kindness and the reasonable handling of civil complaints according to laws and regulations. In order to analyze the environment of the NPS' customer service providers, 5.583 branch employees working at the National Pension Service and 407 call center employees were surveyed online using the questionnaire function of the Enterprise resource planning system. The contents of the survey consisted of a survey on customer-facing employees, the level of awareness of customer-facing workers protection measures, and opinions on improvement and supplementation related to customer-facing workers protection measures. As a result of the survey, 72.8% of the total respondents experienced grievance complaints, and the proportion of call center employees was even higher at 89.0%. In addition, both the branch and the call center had the largest share of complaints about obstruction of business, unreasonable demands, abusive language, and verbal abuse. More than 40% of call center employees in their 20s and 30s experienced the highest frequency of complaints 13 or more times a year. The most difficult thing in the process of responding to complaints was that both branch offices and call centers had insufficient psychological recovery time, lack of space, and lack of help from colleagues and superiors. Based on the survey analysis, it is suggested to establish a countermeasure through case analysis rather than the right to suspend work for civil complaints that cannot be handled, such as customized manuals and action strategies for the age group with high grievance complaints.

Objectives: This study aimed to examine the opinions of registered dental hygienists (RDH) and dental hygiene students (DHS), professionals who can practice visiting oral health care (VOHC), and the demand for specialized training courses of RDH for VOHC. Methods: Using a Google online survey, 125 RDH and 106 DHS personnel were surveyed on their perception of VOHC and the operation of special training courses. Results: RDH (97.6%) and DHS (96.1%) agreed that they needed VOHC for older people. Moreover, the qualification course for specialized training for VOHC was considered necessary. Regarding the appropriate curriculum, RDH preferred training programs comprising 2-hours classes over 6 months and 15 weeks and so on, and DHS preferred 3 hours classes over 6 months and 15 weeks and so on. Regarding the desired working type, the RDH preferred the half-day system, whereas the DHS preferred the alternate-day system. The Korean Dental Hygienists Association was intended for human resource development. They agreed that continuing education was necessary when working as a visiting RDH, and many responded that they would participate if a specialized training course was opened. Conclusions: RDH and DHS have a high level of awareness of the importance and necessity of VOHC, and consider a specialized training qualification course necessary for efficient VOHC.

In large-scale computing, cloud computing plays an important role by sharing globally-distributed resources. The evolution of cloud has taken place in the development of data centers and numerous servers across the globe. But the cloud information centers incur huge operational costs, consume high electricity and emit tons of dioxides. It is possible for the cloud suppliers to leverage their resources and decrease the consumption of energy through various methods such as dynamic consolidation of Virtual Machines (VMs), by keeping idle nodes in sleep mode and mistreatment of live migration. But the performance may get affected in case of harsh consolidation of VMs. So, it is a desired trait to have associate degree energy-performance exchange without compromising the quality of service while at the same time reducing the power consumption. This research article details a number of novel algorithms that dynamically consolidate the VMs in cloud information centers. The primary objective of the study is to leverage the computing resources to its best and reduce the energy consumption way behind the Service Level Agreement (SLA)drawbacks relevant to CPU load, RAM capacity and information measure. The proposed VM consolidation Algorithm (PVMCA) is contained of four algorithms: over loaded host detection algorithm, VM selection algorithm, VM placement algorithm, and under loading host detection algorithm. PVMCA is dynamic because it uses dynamic thresholds instead of static thresholds values, which makes it suggestion for real, unpredictable workloads common in cloud data centers. Also, the Algorithms are adaptive because it inevitably adjusts its behavior based on the studies of historical data of host resource utilization for any application with diverse workload patterns. Finally, the proposed algorithm is online because the algorithms are achieved run time and make an action in response to each request. The proposed algorithms' efficiency was validated through different simulations of extensive nature. The output analysis depicts the projected algorithms scaled back the energy consumption up to some considerable level besides ensuring proper SLA. On the basis of the project algorithms, the energy consumption got reduced by 22% while there was an improvement observed in SLA up to 80% compared to other benchmark algorithms.

Sterile alpha motif (SAM) domains bind to various proteins, lipids, and RNAs. However, these domains have not yet been analyzed as prognostic biomarkers. In this study, SAM domain containing 13 (SAMD13), a member of the SAM domain, was evaluated to identify a novel prognostic biomarker in various human cancers, including hepatocellular carcinoma (HCC). Moreover, we identified a correlation between SAMD13 expression and immune cell infiltration in HCC. We performed bioinformatics analysis using online databases, such as Tumor Immune Estimation Resource, UALCAN, Kaplan-Meier plotter, LinkedOmics, and Gene Expression Profiling Interactive Analysis2. SAMD13 expression in HCC samples was significantly higher than that in normal liver tissue; additionally, SAMD13 was higher in primary tumors, various stages of cancer and grades of tumor, and status of nodal metastasis. Higher SAMD13 expression was also associated with poorer prognosis. SAMD13 expression positively correlated with CD8+ T cells, CD4+ T cells, B cells, neutrophils, macrophages, and dendritic cells. In the analysis of SAMD13 co-expression networks, positively related genes of SAMD13 were associated with a high hazard ratio in different types of cancer, including HCC. In biological function of SAMD13, SAMD13 mainly include spliceosome, ribosome biogenesis in eukaryote, ribosome, etc. These results suggest that SAMD13 may serve as a novel prognostic biomarker for HCC diagnosis and provide novel insights into tumor immunology in HCC.

The novelty in the present search, the Soda-Lime-Silica (SLS) glass waste to prepare free lead glass shielding was used in order to limit the accumulation of glass waste, which requires extensive time to decompose. This also saves on the consumption of pure SiO₂, which is a finite resource. Furthermore, the combining of BaO with Bi₂O₃ into a glass network leads to increased optical properties and improved attenuation. The UV-Visible Spectrophotometer was used to investigate the optical properties and the radiation shielding properties were reported for current glass samples utilizing the PhysX/PDS online software. The optical property results indicate that when BaO content increases in glass structure, the Urbach energy ΔE, and refractive index n increases while the energy optical band gap E_opt decreases. The result of the metallisation criteria (M) revealed that the present glass samples are nonmetallic (insulators). Furthermore, the radiation shielding parameter findings suggest that when BaO was increased in the glass structure, the linear attenuation coefficient and effective atomic number (Z_eff) rose. But the half-value layer HVL declined as the BaO concentration grew. According to the research, the glass samples are non-toxic, transparent to visible light, and efficient radiation shielding materials. The Ba5 sample is considered the best among all the samples due to its higher attenuation value and lower HVL and MFP values, which make it a suitable candidate as transparent glass shield shielding.

The purpose of this study is to identify the characteristics of school library services using the RGT (repertory grid technique), and to examine whether there are differences in the perceptions and internal experiences of school library services between human resources (librarian teachers, subject teachers, and librarians). I used indicators such as element intensity, construct extremity, discrepant constructs, and implicative dilemmas to analyze the characteristics of school library services. The elements of the repertory grid were set to 9, and 14 constructs were set through focus group interviews with 3 librarian-teachers. The GRIDCOR 6.0, which can be accessed online, was used to complete the repertory grid for 30 graduate students of the College of Education, and 6 of them were selected and analyzed, considering the demographic characteristics. From the perspective of element intensity, it was found that the following school library services are important and influential: resource management, teacher-librarian collaboration, and reading and information counseling services. The clarity of one's role, the actual performance, and self-regulatory ability were ranked high from the perspective of constructs intensity.

Background: This study aims to investigate the perceptions of dentists and dental hygienists regarding quality dental job conditions and to identify differences in perceptions based on job type. Methods: As a result of conducting face-to-face and online surveys, data from a total of 132 people were analyzed. In order to investigate the perception of quality job conditions, the importance of a total of 13 items was investigated, and the work policies and job satisfaction of the current workplace were examined. Since the data did not follow a normal distribution, a non-parametric test, the Mann-Whitney U test, was performed. Results: Both dentists and dental hygienists perceived income and working hours to be of priority importance for quality job conditions. Dental hygienists valued holiday support and welfare, human relations, and personal development potential more than dentists (p<0.05). Looking at differences by job type, dental hygienists rated all conditions as more important than dentists except income, indicating a statistically significant difference (p<0.05). In terms of the work policies, 96.2% of the practices in the study were required to have the four types of social security contributions, but fewer had flexible working hours (19.7%), healthcare support (23.5%), and incentives (25.0%). Of the participants, 60.6% had parental leave available at their workplace, and dental hygienists had statistically significantly higher job satisfaction when parental leave was available (2.57 points) than when it was not (p<0.05). Conclusion: Quality dental jobs are an important factor in keeping workers happy and maintaining an efficient practice. Dental practice owners need to pay attention to the quality of jobs required by the dental workforce, provide flexible working hours and welfare programs such as parental leave, and create a workplace atmosphere and human resource management system that supports the use of these programs.
